To all whom z't may concern:

Be 1t known that 1, WILLIAM ErSMITH,

a citizen of the United States, residing at Lynn, county of Essex, State of lVIassachusetts, have invented an Improvement in Beading-Machines, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to beading machines such as are used for pressing or setting. a folded edge of fabric, leather, etcL, andthe object of the invention is to provide a novel beading machine having provision for heating the anvil or worksupport. The advane tage of this is that the fold or bead will be more permanently setdue to the fact that the goods become heated slightly by contact with the heated anvil as they are operated upon.

In the embodiment of the invention herein illustrated, the heating element is constructed to encircle or surround the anvil, andit is so supported that it is not affected by the hammer-like blow which is given to the anvil by the hammer or pressing element; 1 In order to give an understanding of my invention, 1 have illustrated in the drawings a selected embodiment thereofwhichwill now be described, after which the novel features will be pointed out in the appended claims.

Figure 1 of the drawingsis a side view of a beading machine embodying my invention;

The anvil is provided with the usual rounded end on which the work rests and the hammer element is shown as carried by an arm orlever 6 pivotally mounted to' the frame at 7 The hammer is constructedto be vibrated rapidly toward and from the anvil 4, and for this purpose the driving shaft is provided with an eccentric 8, the eccentric strap 9 of which is connected to the lever 6 by the link or connection 10.

element 5 will be given a vibrating moveit merit-toward and from the anvil 4, and as the folded edgeof the sheet material is fed over the anvil, the hammer 5 will give" said edge a series of repeated blows in rapid succession, thereby setting'the fold.

Theparts thus far described are ormay be all as usual in beading machines of-this nature and form no vention.

As stated above, my present invention relates to a means for heating the anvil'4 so that as the work is fed over the anvil, it will be heated somewhat, thus making the action of the machine more effective in giv ing a permanent set to the folded edge. 1 will preferably use electrical heating means for this purpose in the form of a heating coil which surrounds the anvil, and in order to prevent injury to the coil by the hammer likeblows which are received by the anvil, I propose to so mount the heating coil that it will not be aflected by the blows of the hammer element 5. p v I The heating coil is shown at 11 and it; is contained within a holder 12 which en circles the anvil 4, the heating coil being confined between the inner wall 13 of the holder and a tubular shell 14. The turns of the heating coil are insulated from the holder by insulation 31 and are insulated from each other by some suitable insulating compound which is a good conductor of heat. The heating coil is connected to feedwires 15 by which a proper amount of electric current is delivered to the coil; The anvil 4 is backed. by a spring '16 which rests on the head 17 of a, stud 18 that is screw-threaded into the frame 1. The holder 12 is formed with a recess19 which not only receives the anvil-4, but also receives thespring 16 abovereferred to. The holder is also formed with'thefiange 20 at its lowerend which engages the under side of the headl7 andwhich retains the holder in place. The outer end of the holder is provided with the inwardly-directed annular flange 21 which overlies'a rib or flange 22 formed 011 the anvil and which thereby. limits the outward movement of the anvil. This flange 21 is shown as formed on a ringlike member 23 which is screw-threaded to the outer end of the holder, this construction being adopted for convenience in manufacture and assembling of the parts. The

holder is also provided with' a positioning pin 2d which-enters a recess 25 formed in of the stud 18, as shown in Fig.2. The

anvil and the holder are so constructed that the anvil can have a limited depressing movementrelative to the holder without bringing the flange 22 against the end 250 ofthe heating coil. The purpose of this construction is to permit the anvil to yield slightly at each blow of the hamnier'independently of the holder, sothat the force of the blow will be received directly'by the anvil and transmitted therefrom through the spring 16 to the frame, instead ofbeing transmitted to the holder 12 or the heating unit 11. The machine is, therefore, capable of continued and rapid operation without danger of injuring the insulation or any other partof theheating unit. a i

It will be noted that the stud l8 is screw threaded lIltOtllG frame 1. The'purpose of this'is to provide for adjusting theanvil and holder bodily relative to the hammer element 5 to correspond to different thicknesses of work. The construction is "such that in all adjusted positions of theanvil the latter is always capable of a limited yielding movement relative to the holder and the heating'unit, and hence thereis no danger of the heating unit becoming injured inany adjusted position of the anvil.

WVhile I have illustrated liereina selected embodiment of my inventiom -I do notwish to beliinit'ed to tlie constiuctional features shown.

I claim:

1. In a beadingmachine, the combination with a frame, of an anvil,- a spring yield ingly sustaining said-anvil, a vibratory hammer, a member encircling the anvil and limiting its: spring-pressed movement; said member being capable of movement relative to the frame, and means carried by said member for heating the anvil. 2. In a beading machine, the combination with a frame, of an anvil, a spring yieldingly sustaining said anvil, a vibratory h ammer, a member encircl-ing the anvil-and limiting its spring-pressed movement, said member being capable of movement relative 'Gopi'es ofst-his patentmay be obtained for .tothe frame in the direction of the movement of the hammer, and means carried by said member for heating'the anvil.

3. In a beading machine, the combination with a frame, of an anvil, a spring yieldsingly sustaining said anvil, a vibratory hamaner cooperating with the anvil, a member encircling the anvil and limiting its'spring- *pressed movement, said member being cabeing yieldable relative to the heating-element under the impact of the hammer element. r
